"The effect of simulated environmental exposure conditions (high heat, freezing temperature, rain, and vacuum pressure) on the performance of a silver-based conductive flexo ink printed on a polyamide (nylon 6,6) substrate was examined. Conductivity, density, color, adhesion, abrasion resistance and creasing were evaluated. The tested environmental variables did not have an effect on the performance quality of silver conductive flexographic ink when printed on a polyamide substrate for the 85-100% solid ink density levels. Rain and temperature had the greatest impact on print performance in the 70-80% tint range. Exposure to these elements affected adhesion properties of the ink to the substrate, which lead to a negative effect on the conductivity and abrasion performance. This study indicated an antenna printed at common ink density levels using a silver-based flexographic printing ink on a polymeric film is a possible solution for the implementation of printed RFID components. This is a manufacturing option that can bring the packaging industry from a "slap and stick" RFID labeling method to an actual inline production method that can be applicable to both primary and secondary package tagging needs. Lastly, the study utilizes common ink testing procedures that will be useful in the development of standards for the production of printed RFID components in packaging applications."--Abstract.
For the continued advancement of the field of printed electronic (PE), there is a need for a better understanding of the interactions between functional inks and substrates, which is required to optimize printability, mechanical, and functional properties for the creation of more robust and efficient printed devices. This body of work aims to advance the knowledge of the material properties of poly-di-methyl-siloxane, PDMS, films, their interactions with flexo inks, and their flexographic printability. As the printing of metals (i.e., Ag & Au) is a known area of interest pertaining to PE, this work focused on the characterization and optimization of the properties known to promote the adhesion between materials, and their effects on the functional performance of printed conductive ink films. PDMS is an especially important substrate for use in the creation of biocompatible sensors and devices, which is an area predicted to experience much growth in the coming years. But, PDMS has known complications pertaining to its printing and adhesion of materials to its surface. To accomplish this goal, four studies were completed: 1- The Characterization of Surface Treated Silica-Filled and Non-Filled Polydimethylsiloxane Films, 2- Use of Atmospheric-Plasma Treatment to alter the Surface Energy of PDMS Films, and 3- Feasibility for the Development of a Repulpable Silicone Release Paper. From these studies, a need for a high throughput processing and production method for rol-to-roll production and printing of thin (
The technical application of screen and stencil printing has been state of the art for decades. As part of the subtractive production process of printed circuit boards, for instance, screen and stencil printing play an important role. With the end of the 20th century, another field has opened up with organic electronics. Since then, more and more functional layers have been produced using printing methods. Printed electronics devices offer properties that give almost every freedom to the creativity of product development. Flexibility, low weight, use of non-toxic materials, simple disposal and an enormous number of units due to the production process are some of the prominent keywords associated with this field. Screen printing is a widely used process in printed electronics, as this process is very flexible with regard to the materials that can be used. In addition, a minimum resolution of approximately 30 µm is sufficiently high. The ink film thickness, which can be controlled over a wide range, is an extremely important advantage of the process. Depending on the viscosity, layer thicknesses of several hundred nanometres up to several hundred micrometres can be realised. The conversion and storage of energy became an increasingly important topic in recent years. Since regenerative energy sources, such as photovoltaics or wind energy, often supply energy intermittently, appropriate storage systems must be available. This applies to large installations for the power supply of society, but also in the context of autarkic sensors, such as those used in the Internet of Things or domestic/industrial automation. A combination of micro-energy converters and energy storage devices is an adequate concept for providing energy for such applications. In this thesis the above mentioned keywords are addressed and the feasibility of printed thermoelectric energy converters and supercapacitors as energy storage devices are investigated. The efficiency of thermoelectric generators (TEG) is low, but in industrial environments, for example, a large amount of unused low temperature heat energy can be found. If the production costs of TEGs are low, conversion of this unused heat energy can contribute to increasing system efficiency. Additionally, printing of supercapacitor energy storage devices increases the usability of the TEG. It is appropriate to use both components as complementary parts in an energy system. Den tekniska tillämpningen av skärm- och stencilutskrift har varit toppmoderna i årtionden. Som en del av den subtraktiva produktionsprocessen av tryckta kretskort spelar exempelvis skärm- och stencilutskrift en viktig roll. I slutet av 1900-talet har ett annat fält öppnat med organisk elektronik. Sedan dess har allt fler funktionella lager producerats med hjälp av tryckmetoder. Tryckta elektronikanordningar erbjuder egenskaper som ger nästan all frihet till kreativiteten i produktutvecklingen. Flexibilitet, låg vikt, användning av giftfria material, enkelt bortskaffande och ett enormt antal enheter på grund av produktionsprocessen är några av de framträdande nyckelord som hör till detta område. Skärmtryck är en allmänt använd process i tryckt elektronik, eftersom processen är mycket flexibel med avseende på material som kan användas. Dessutom är en minsta upplösning på cirka 30 µm tillräckligt bra. Bläckfilmens tjocklek, som kan styras över ett brett område, är en extremt viktig fördel med processen. Beroende på viskositeten kan skikttjockleken på flera hundra nanometer upp till flera hundra mikrometer realiseras. Energikonvertering och lagring har blivit ett allt viktigare ämne de senaste åren. Eftersom regenerativa energikällor, såsom fotovoltaik eller vindkraft, ofta levererar energi intermittent, måste lämpliga lagringssystem vara tillgängliga. Detta gäller stora installationer för samhällets strömförsörjning, men också inom ramen för autarkiska sensorer, som de som används i saker av saker eller inhemsk / industriell automation. En kombination av mikroenergiomvandlare och energilagringsenheter är ett lämpligt koncept för att tillhandahålla energi för sådana applikationer. I denna avhandling behandlas ovan nämnda nyckelord. Genomförbarhet av tryckta termoelektriska energiomvandlare och superkapacitorer som energilagringsenheter undersöks. Effektiviteten hos termoelektriska generatorer (TEG) är låg, men i industriella miljöer kan exempelvis en stor mängd oanvänd låg temperatur värmeenergi hittas. Om produktionskostnaderna för TEG är låga kan konvertering av denna oanvända värmeenergi bidra till ökad systemeffektivitet. Dessutom ökar utskrift av superkapacitorer användbarheten hos TEG. Det är lämpligt att använda båda komponenterna.

Chipless RFID based on RF Encoding Particle: Realization, Coding and Reading System explores the field of chipless identification based on the RF Encoding Particle (REP). The book covers the possibility of collecting information remotely with RF waves (RFID) with totally passive tags without wire, batteries, and chips, and even printed on paper. Despite the many benefits of RFID, deployment is still hindered by several economic and technological factors. Among these barriers are the high cost of tags, lack of reliability and security in the information contained in the RFID chip, and how tags are 'recycled.' This book focuses on the development of chipless RFID tags, representing a new family of low cost tags. With this technology information is extracted from the electromagnetic response of the tag, which depends only on its geometry. Various solutions have been developed by the authors to increase the amount of information, reduce the surface of the tag, or improve the robustness of detection. Considerations such as realization using paper substrate, the development of a low cost detection system, and measurements in a real environment have been addressed for practical implementation. - Introduces the chipless RFID REP approach as compared to classical chipless RFID, RFID, and barcode technologies - Includes a demonstration of the practical and economic potential of chipless RFID technology, with detailed presentations and discussions of different test benches and comparisons - Presents in detail numerous examples of chipless tags that are able to tackle specific problems: sensitivity of detection, encoding density, robustness of detection, problem of tag orientation, tags and reader cost, and compliance with emission standards - Focuses on the development of chipless RFID tags, representing a new family of low cost tags

This book has been a long time in the making. Since its beginning the concept has been refined many times. This is a first attempt at a technical book for me and fortunately the goals I have set have been achieved. I have been involved in water based ink evaluation since its unclear begin nings in the early 1970s. This book is fashioned much like a loose-leaf binder I had put together for early reference and guidance. The format has worked for me over the years; I trust it will work for you. I would like to thank the many people who made this book possible, particularly Blackie Academic & Professional for their saint-like patience. Thanks again to W.B. Thiele (Thiele-Engdahl), to Lucille, my wife, and to James and Frank, my two boys. A final and special thank you to Richard Bach who taught me there are no limits.
